Nothing to book, just show up

One of 1,623 federal campgrounds where the site still goes to whoever pulls in first. Get there before noon on a summer weekend.

recreation.gov publishes no availability for a campground you can’t reserve, so there’s no thirty-night reading to draw here. The season bar above is what the agency does publish.

What you actually pay

The sign priceNational Park Service
The National Park Service publishes no per-night rate for this campground that we can read, so there’s no sign price to print. That’s a gap in the record, not a free campground.
The booking feerecreation.gov
Nothing. This campground takes no bookings, so there’s no reservation fee to pay.
What a stay costs
The agency publishes no nightly rate for this campground, so there’s no total to show.
